Argon (Ar) is the third most abundant gas in the atmosphere and accounts for 0.934% in the air. The name of this gas comes from the Greek word for "inactive". Indeed, argon is in chemistry an inert gas. It has low thermal conductivity but has electromagnetic properties (ionization and / or emission spectrum) that can be used for a wide variety of applications.
Air is a combination of gases, which includes nitrogen (78%), oxygen (21%) and argon (0.9%). The remaining 0.1% residue is mainly carbon dioxide, neon, helium, krypton and xenon.
Argon is most commonly produced together with the production of pure oxygen using the cryogenic distillation method in special equipment. The air separation plant uses a heat treatment process called cryogenic rectifier to separate independent gas molecules from each other to produce pure nitrogen, oxygen and argon in liquid form. Since the boiling temperature of argon is so close to oxygen, the separation of pure argon from oxygen requires a lot of distillation.

Argon is a colorless, odorless, tasteless gas. Although it is non-toxic, argon can become an asphyxiant by displacing air or liquefying oxygen. Additionally, exposure to liquid argon can cause frostbite and skin irritation. To avoid dangerous harmful effects, manufacturers and consumers should strictly follow the safety instructions for the storage and use of argon.
